Perhaps you should try some spelling variations:
doanh nhung » doanh thuong, doanh nhan, doan hung
doanh chung » doanh thuong, doan hung, doanh chuoi
hanh trinh » canh tranh, hanh chinh
theo chu » theo chieu, cho chu, chao chu
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu thich - hanh trinh ((doanh nhung) OR (doanh chung)) cong dan toan cao~.
• Adding a wildcard symbol may retrieve word variants: theo chu thich - hanh trinh ((doanh nhung) or (doanh chung)) cong dan toan cao*.
